DCAF11 encodes a WD repeat-containing protein that interacts with the COP9 signalosome, a macromolecular complex that interacts with cullin-RING E3 ligases and regulates their activity by hydrolyzing cullin-Nedd8 conjugates. Additionally we are shipping DCAF11 Proteins (6) and many more products for this protein.

Here, the authors demonstrated that CUL4B forms an E3 ligase with RBX1 (RING-box 1), DDB1 (DNA damage binding protein 1), and DCAF11 (DDB1 and CUL4 associated factor 11) that promotes the ubiquitination of p21(Cip1) and regulates cell cycle progression in human osteosarcoma cells.
CRL4(WDR23) is required for efficient histone mRNA 3' end processing to produce mature histone mRNAs for translation. CRL4(WDR23) binds and ubiquitylates SLBP in vitro and in vivo, and this modification activates SLBP function in histone mRNA 3' end processing without affecting its protein levels.
CRL4-DCAF11 mediates the degradation of SLBP at the end of S phase and this degradation is essential for the viability of cells.
ur results identify WDR23 as an alternative regulator of NRF2 proteostasis and uncover a cellular pathway that regulates NRF2 activity and capacity for cytoprotection independently of KEAP1.
Includes the functional characterization of a similar protein in C. elegans and comparison to the human protein.
This gene encodes a WD repeat-containing protein that interacts with the COP9 signalosome, a macromolecular complex that interacts with cullin-RING E3 ligases and regulates their activity by hydrolyzing cullin-Nedd8 conjugates. Multiple alternatively spliced transcript variants have been found for this gene.
